Photo controls on PC

I have found every control except 1. The up/down elevation. W,A,S,D,Q,E,Z,C and the Arrow keys all have functions. None of which are up/down on a vertical plane. Any help is appreciated.

It was page up and page down or something…it is possible to go up and down at least a meter or so.

TY very much! Not sure how i didnt notice that before.
